For the development of next-generation electronics, optoelectronics, and nanotechnology

Tin(IV) sulfide (also known as tin disulfide SnS₂), CAS number 1315-01-1, is a layered metal dichalcogenide semiconductor with a similar chemical and crystal structure to that of molybdenum disulfide (MoS₂). In each individual layer, Sn is sandwiched between two S layers with strong covalent bonding, whereas individual mono-layers are held by weak van der Waals forces. Individual layers break free when weak van der Waals forces are overcome by either physical or chemical exfoliation.

Like many other two dimensional semiconductors, SnS₂ can undergo exfoliation to form atomic-layer sheets that have applications in FETs, photovolatic solar cells, sensors and photocatalyst applications.

SnS₂is an n-type semiconducting material that has a hexagonal CdI₂-type structure.

*Typical representative size, areas/dimensions may vary

Bulk single tin(IV) sulfide crystal is most commonly used as sources from which single or few-layer sheets can be obtained via either mechanical or liquid exfoliation.

Tin(IV) sulfide powder can also be used to prepare SnS₂ nanosheets and nanoparticles by liquid-exfoliation (normally assisted by sonication). Cu intercalated bilayer SnS₂ displays a hole field-effect mobility of ~40 cm² V⁻¹s⁻¹, and Co-SnS₂ exhibits a metal-like behaviour with sheet resistance comparable to that of few-layer graphene.

Structure of Tin(IV) Sulfide

Tin(IV) sulfide (SnS₂) has a layered structure, where each Sn ion coordinates to six S ions in a regular octahedron. Each sheet of Sn atoms is sandwiched between two sheets of S atoms, and each S-Sn-S layer is held by weak van de Vaals interactions.

SnS₂ crystallises with a standard hexagonal crystal structure (2H-SnS₂) which is identical to that of 1T-MoS₂. Monolayers of 2H-SnS₂ are stacked precisely on top of one another to form the 2H-polytype of bulk SnS₂. It is noted that the 2H-SnS₂ structure is different from that of 2H-MoS₂, where the Mo atom possesses a trigonal prismatic coordination instead.

Properties of 2D Tin(IV) Sulfide

After exfoliation of crystals or powder, tin(IV) sulfide typically has the following properties:

Hexagonal (2H) structure (space group: P3m1)
Earth-abundant, non-toxic, and chemically stable
n-type semiconducting material with band-gap of 2.2–2.35 eV

Applications of Tin(IV) Sulfide

Tin(IV) sulfide single crystals can be used to prepare monolayer and few-layer SnS₂ by mechanical or liquid exfoliation. Tin(IV) sulfide powder is suitable for liquid chemical exfoliation to prepare SnS₂ nanosheets and nanoparticles down to few-layer films.

With high sensitivity and high surface activity, exfoliated SnS₂single or few-layer ultra-thin films from bulk crystal and powder have also been used in applications ranging from light emitters, field effect transistors (FETs), gas sensors, photodetectors, thermoelectric photovoltaic and energy storage devices such as for applications Li-ion batteries

With a band-gap of 2.2–2.35 eV, hexagonal SnS₂ has been used for efficient visible-light water-splitting. It is earth-abundant, non-toxic, and chemically stable in both acidic or neutral aqueous solutions. Physical or liquid exfoliated SnS₂single or few-layer ultra-thin films from bulk crystal and powder have also been used in applications ranging from light emitters, field effect transistors (FETs), gas sensors, photodetectors, thermoelectric photovoltaic and energy storage devices

Viscoelastic Transfer of 2D Material Using PDMS

Viscoelastic transfer using polydimethylsiloxane (PDMS) stamps is one of the methods used for the deterministic placement of 2D materials and the fabrication of van der Waals heterostructures. It relies on the viscoelasticity of PDMS, which behaves as an elastic solid on short time scales, but as a viscous fluid on long time scales.
